Chemistry Consortium NFDI4Chem - Poster from the 1st NFDI-Conference
Herres-Pawlis, Sonja; Koepler, Oliver; Steinbeck, Christoph
On this poster we present the chemistry consortium NFDI4Chem for the german national research infrastructure (NFDI). The NFDI4Chem is a grassroots movement of researchers, infrastructure experts and actors of learned societies from all disciplines of chemistry. The vision of NFDI4Chem is the application of digitisation principles to all key steps of research in chemistry. We have identified six key objectives for the development and maintenance of a national research data infrastructure for chemistry in germany, and to enable innovative services and science based on research data. Objectives range from initiating community processes for minimum information standards for data and machine-readible metadata, fostering the application of Electronic Lab Notebooks (ELN)s, software, tools and APIs of devices towards an embedded, digital information architecture in the lab, to the creation of an increased awareness of research data management and FAIR data principles in the chemistry community. We describe our planned contribution to the overarching NFDI-structure and expected synergies with other consortia. First results of a user survey about the current application research data management are shown. The poster was presented on the 1st NFDI-Conference, 13-14th May 2019 in Bonn, Germany.

On August 17, 2017 at 12:41:04 UTC the Advanced LIGO and Advanced Virgo gravitational-wave detectors made their first observation of a binary neutron star inspiral. The signal, GW170817, was detected with a combined signal-to-noise ratio of 32.4 and a false-alarm-rate estimate of less than one per 8.0 x 10(4) years. We infer the component masses of the binary to be between 0.86 and 2.26 M-circle dot, in agreement with masses of known neutron stars. Restricting the component spins to the range inferred in binary neutron stars, we find the component masses to be in the range 1.17-1.60 M-circle dot, with the total mass of the system 2.74(-0.01)(+0.04) M-circle dot. The source was localized within a sky region of 28 deg(2) (90% probability) and had a luminosity distance of 40(-14)(+8) Mpc, the closest and most precisely localized gravitational-wave signal yet. The association with the gamma-ray burst GRB 170817A, detected by Fermi-GBM 1.7 s after the coalescence, corroborates the hypothesis of a neutron star merger and provides the first direct evidence of a link between these mergers and short gamma-ray bursts. Subsequent identification of transient counterparts across the electromagnetic spectrum in the same location further supports the interpretation of this event as a neutron star merger. This unprecedented joint gravitational and electromagnetic observation provides insight into astrophysics, dense matter, gravitation, and cosmology.

On August 14, 2017 at 10:30:43 UTC, the Advanced Virgo detector and the two Advanced LIGO detectors coherently observed a transient gravitational-wave signal produced by the coalescence of two stellar mass black holes, with a false-alarm rate of less than or similar to 1 in 27 000 years. The signal was observed with a three-detector network matched-filter signal-to-noise ratio of 18. The inferred masses of the initial black holes are 30.5(-3.0)(+5.7)M(circle dot) and 25.3(-4.2)(+2.8) M-circle dot (at the 90% credible level). The luminosity distance of the source is 540(-210)(+130) Mpc, corresponding to a redshift of z = 0.11(-0.04)(+0.03). A network of three detectors improves the sky localization of the source, reducing the area of the 90% credible region from 1160 deg(2) using only the two LIGO detectors to 60 deg(2) using all three detectors. For the first time, we can test the nature of gravitational-wave polarizations from the antenna response of the LIGO-Virgo network, thus enabling a new class of phenomenological tests of gravity.

Kompetenzzentrum Digitales Handwerk
Der digitale Wandel ist ein globaler Innovationsprozess, der massive Auswirkungen auf alle Bereiche der Wirtschaft und Gesellschaft hat. Unter dem Begriff Industrie 4.0 wird die Digitalisierung und Vernetzung der Wertschöpfungsketten diskutiert; dies hat weltweite Auswirkungen auf alle beteiligten Unternehmen und Organisationen. Durch den Einsatz moderner Produktions- und Automatisierungstechnologien sowie von Informations- und Kommunikationstechnologien (IKT) lassen sich die Arbeitsstrukturen innerhalb sowie die Kooperationsmöglichkeiten zwischen Unternehmen, Kunden und anderen Wirtschaftsakteuren nachhaltig erweitern, in Echtzeitverfolgen und verändern. Damitentstehen auch neue Anforderungen an die Kooperationsbereitschaft zwischen Unternehmen sowie innerhalb ihrer Belegschaften.
